Turtle is a C++17-based lightweight network library for web server on Linux. It abstracts the tedious manipulations on the TCP socket into low coupling and highly extensible framework. It allows a fast custom server side setup where the business logic could be specified for each client TCP connection in the form of a callback function.

• Set non-blocking socket and edge-trigger handling mode to support high concurrency workload
• Support HTTP GET/HEAD request & response
• Support dynamic CGI request & response
• Support MySQL Database interaction
• Support Timer to kill inactive client connections to save system resources
• Support asynchronous consumer-producer logging
